BACKGROUND OF THE INVENTION

1. Technical Field

The present utility model relates to a hair dryer or the fitting for ahair dryer in the field of daily necessities, more specifically, to anairflow concentrator sleeved or fixed onto a hair dryer.

2. Description of Related Art

A hair dryer is a hairdressing apparatus commonly seen in hair salons orat home for private use, in order to rapidly dry hair. Generally, tomeet the needs of different using situations, an airflow concentratorcan be arranged on the air supply outlet of the hair dryer to achievediversified hairstyles.

However, the airflow concentrator (also known as airflow nozzle/airnozzle) currently available in the market is basically made of plastic,and with single function only (airflow concentration generally).Moreover, considering the user's normal using demands, the top of theairflow concentrator often directly contacts hair and slides (forexample, straighten long hair by means of the airflow concentrator). Theall-plastic airflow concentrator, on one hand, is easy to createfriction (rubbing effect) with hair and damage the hair cuticle so thathair becomes injured; on the other hand, heat that is originated fromthe hair dryer may partly dissipate after passing the airflowconcentrator, thus causing that repeated operation on hair is requiredfor getting desired effect. Therefore, it is necessary to develop anairflow concentrator capable of reducing heat loss and damage to hairwhich overcomes the structural drawbacks of the airflow concentrators inthe prior art.

BRIEF SUMMARY OF THE INVENTION

In view of the deficiencies in the prior art, the present invention aimsat providing an airflow concentrator for a hair dryer with a rollingmechanism mounted on the top so as to, on one hand, reduce contactbetween hair and the airflow concentrator to further protect haircuticle; on the other hand, retain heat in the hair dryer, with the helpof the metal rolling mechanism, to further reduce loss and realizeperm-like effects by concentrating heat on hair directly.

To realize the objective described above, the present utility modelemploys the following technical solution:

an airflow concentrator for a hair dryer, comprising an airflowconcentrator base, wherein the base can be sleeved onto the air supplyoutlet of the hair dryer at the bottom, characterized in that, a rollingmechanism is further included, two sets of through holes of positionalcorrespondence are provided on the two sides of the top of the base, andthe rolling mechanism is mounted in the top of the base by means of thetwo sets of through holes of positional correspondence and realizesrolling movement; the rolling mechanism includes a first rolling wheel,a second rolling wheel, a first rotation shaft, a second rotation shaft,rolling wheel caps and a shaft rivet, wherein the first rolling wheeland the second rolling wheel are provided with a hollow cylindrical slotbody respectively and used to make the two ends achieve connectivityrespectively, the rolling wheel caps which are mounted on the two endsof the first rolling wheel and the second rolling wheel are providedwith a hollow cylindrical open-slot respectively and used to make thetwo ends achieve connectivity; the first rotation shaft and the secondrotation shaft extend into the cylindrical slot body of the firstrolling wheel and the second rolling wheel after passing the throughholes of one side on the top of the airflow concentrator and thecylindrical open-slot on one end of the rolling wheel caps respectively,the shaft rivet extends into the cylindrical open-slot on the other endof the rolling wheel caps after passing the through holes of the otherside on the top of the airflow concentrator; a slot fit for the size andshape of the shaft rivet is arranged on one end of the first rotationshaft and the second rotation shaft, and the shaft rivet and the slotare spliced together in the cylindrical open-slot of the rolling wheelcaps.

It shall be noted that, the rolling wheel caps include a cap part and acap body, wherein the cap body has an outer diameter less than the innerdiameter of the cylindrical slot body of the first rolling wheel and thesecond rolling wheel, and the cap body is closely connected with theinner diameter of the cylindrical slot body; the outer diameter of thefirst rotation shaft, the second rotation shaft and the shaft rivet isless than the inner diameter of the cylindrical open-slot respectively.

In the prior art, to achieve better thermal conduction, the air supplyoutlet of the airflow concentrator must be perpendicular to the hairsurface and the hand must hold it for a long time, so it is prone tocause hand fatigue. To reduce the occurrence of such cases, the top ofthe base is configured to be a slope structure, the second rolling wheelis lower than the first rolling wheel, thus it is possible to get betterheat without the necessity of keeping it vertical to hair surface inuse; secondly, when the airflow concentrator in the prior art is in use,the body must directly contact hair, which may lead to damage to thehair cuticle on the hair surface. Therefore, the rolling mechanism inthe present utility model after assembly is slightly higher than theslope structure to avoid damage to hair (reduce friction and rubbingeffect).

It shall be also noted that, as a preferable technical solution, toprevent hair from getting in the rolling mechanism in use, an isolatingplate that extends into the top of the base downwards is arranged in thebase; the isolating plate is located between the first rolling wheel andthe second rolling wheel.

It shall be further noted that, to reduce the damage of mechanicalrubbing effect from conventional plastic air concentrator to haircuticle and better concentrate heat of the hair dryer, the first rollingwheel and the second rolling wheel are made of metals, such as aluminum.

As a preferable technical solution, to further increase the areacontacting hair surface and enhance the concentrated heat effect, thefirst rolling wheel and the second rolling wheel can be replaced byseveral rolling wheel to realize another type of improvement.

The following is an alternative structure of the airflow concentratorfor the present utility model. It shall be noted that,
